STILL AND FILTER.

SPECIFICATION forming part of Letters Patent No. 318,698, dated May 26,1885.

Application filed December 26, 1883. Nomodel) To all whom, it mayconcern:

Be it known that we, RoLLIN C. CLARK and MURRAY H. WARREN, of Corry, inthe county of Erie and State of Pennsylvania, have invented certain newand useful Improvements in Stills and Filters; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

Our invention relates to an improvementin stills and filters, designedmore especially for the reduction or refining of hydrocarbon oil, and isadapted more especially to the use of crude petroleum oil or lighthydrocarbon for fuel.

Our invention consists in the parts and combinations of parts, as willbe more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section of aheat-generator and the plant in which are located the still and filter,shown in elevation. Fig. 2 is a vertical section of a breaker, and inelevation the pipes constituting an apparatus for burning crude-petroleum-oil.

A represents a still located in the chamber A, and resting upon thesupports a, that elevate the still some distance above the floor of thesaid chamber. A bridge-wall, (1, extends under the still and up thesides thereof, and closes the openingbetween the still and the walls ofthe chamber, and divides the chamber into two parts, so that the heat inpassing from one part of the chamber to the other part must pass uparound one side and over the top of the still and down the other side ofthe still in its route to the chimney F.

B is the heat-generating furnace, extending up through the fioor of thechamber A, and arched at the top, as shown, and provided with openingson opposite sides for discharging the air in lateral directions into thechamber A.

In the position of parts as shown the products of combustion enter thesaid chamber onthe left-hand side of the bridge-wall a, and must firstpass up around the sides and over the top of the still, then down aroundthe other side of the still on the right-hand side of the bridge-wall,then through an orifice, f, into the chimney F.

G are aircl1ambers provided with openings 0 and passage-ways a, leadinginto the chamber O, that surrounds all but the upper portion of thegenerator B. Air admitted through the opening 0 passes to the chamber 0,and is then heated by radiation from the generator, and passes onthrough the duct 0 at the upper end of which it is joined by a currentof air admitted by a damper through the orifice discharge-pipe, j,leading into the trough K,

that, being located over the end of the duct H, is heated, therefore,sufficiently for the purpose for which it is used. There is also anopening, 11, at the top of the chamber, provided with a damper, by meansof which surplus heat may be discharged. Other openings provided withdampers may be had to admit air to cool the filter when required. Thusit will be seen that by raising the damper h communication between thechamber inclosing the filter and the hot-air flue or duct H is openedand the hot air permitted to e11- ter said chamber and heat the filterto the desired degree. After the proper temperature is reached it can bemaintainedjfby opening one or more dampers for the escape of any excessof hot air entering the chamber.

X is a tank set in the heating-chamber Y, into which the filtered oilmay be drawn and kept warm by means of heated air admitted in the saidchamber through the duct or passage-way g, which can be closed by slideor damper 71 when it is desired to exclude the hot air.

L is a casing extending from the outside of the structure to the top ofthe still, and inclosing the man-hole Z, by means of which access may behad to the inside of the still.

The walls of the entire structure are made preferably of brick.

When the products of combustion are admitted directly into the chambersurrounding the still, it is essential that fuel be used that willproduce little smoke, soot, or other refuse, as this would soon clog thesaid cham her and adhere to the still, so that the device would becomeinoperative. \Ve have therefore invented what is known as a breaker, bymeans ofwhich we are enabled to use crude petroleum-oil for fuel.

0, P, and Q, are pipes, each provided with a valve, and respectively forsteam, oil, and air, that join the pipe R in such a manner that thecurrent of steam through the pipe 0 draws with it the-oil and air thatare ignited at the mouth of the pipe R, the flame of which is projectedinto the breaker M, when the jet of flame impinging against the wallsthereof is broken and discharged through the side openings, N. By meansof breaking the flame and changing the direction thereof, as aforesaid,a

large amount of air is comrningled with the flame, greatly increasingthe degrees of heat, and thereby lessening the amount of oil required.The breaker is built preferably of fire-brick, and closed 011 top and atthe ends,

' except the orifice where the flame enters.

\Vith this arrangement for supplying heat little or no smoke or sootpasses beyond the generator B. Such impurities as there may be in theoil are discharged at the mouth of the tube R, or in or about the saidbreaker.

The supply of steam, oil, or air may, any or all of them, be regulatedat pleasure and the heat instantly increased or diminished.

The fire may be started at a moment s notice and extinguished asquickly, and a moment after extinguishing the fire a current of air maybe admitted into the generator, and will, falling in the route, travelby the heat to the chimney F, and soon cool the still, so that it may beentered if required.

WVe make no claims to construction or arrangement of the pipes O, P, Q,and R, or to a still or filter inclosed respectively by air-- chambersand heated with air.

\Vhat we claim is 1. In an oil-still, the combination, with aheating-chamber and a still located therein, of a heat-generator locatedwithin an airchamber and communicating directly with saidheatingchamber, a hot-air flue leading from said air-chamber, and achimney in open relation with the heating-chamber, substantiall y as setforth.

2. The combination, with a heat-generator located within an air-chamberand communicating with an upper chamber, and a still situated in saidupper chamber over the generator, of a hot-air flue leading from theairehamber upwardly alongside of the upper chamber, and a flue orchamber opening into the outer air and communicating with the hot airflue, substantially as set forth.

3. The combination, with a heat-generator, a heating-chamber locatedover said generator and in communication therewith, and a metal cover ortop for said chamber, of a filter and the flues c and E, leading fromaround the heating-chamber to the filter, substantially as set forth.

4. The combination, with a still inclosed within a heating-chamber, ametal floor constituting the top of said chamber, and afilter. of apassage-way for conducting air over said metal floor to the filter,whereby the air is heated on its passage to the filter, substantially asset forth.

5. The combination, with a still inclosed within a heating chamber, anair-chamber located below said heating-chamber, and a chimneycommunicating with the heating chamber, of a heat-generator locatedpartly withinthe air-chamber and terminating within the heating-chamber,and a hydrocarbonburner constructed substantially as described .andlocated within said generator, substantially as set fortln 6. Thecombination, with a heating-chamber, a still located therein, and aheat-generator located below said heating-chamber, of a filter inclosedwithin a chamber, a flue, E, passing directly over the heating-chamber,a flue connecting the heat-generator and filterinclosing chamber andconnecting with the flue E, and a damper for closing the opening betweenthe fines and filter-inclosing chamber, substantially as set forth.

In testimony whereof we sign this specificaiion,in the presence of twowitnesses,this 11th day of December, 1883.
